I recommend you don't use 2 dragon flying types like Salamence and dragonite on the same team. Since Salamence is better, I'd choose that over dragonite.

It's a bad idea to have 2 Pokemon if the same species on a single team. So just use on greninja.

As for rotom, refrigerator is actually the worst of all rotom forms. I say use rotom wash or rotom heat. Rotom wash is better but generally you don't want 2 Pokemon of the same type on your team.

Now that's 3 Pokemon on your team, you have 2 sweepers and a tank/wall(depends on how you plan to use rotom). Maybe get a wall breaker like mega charizard y. With the last two Pokemon idk a support Pokemon? Whimscott is good with prankster.

Last pokemon is your choice but try not to double up on a type
